A method and apparatus for screening, sensing, or diagnosing disease states by obtaining a plurality of electrical impedance data measurements in organized patterns from two anatomically homologous body regions, one of which may be affected by disease. One subset of the data so obtained is processed, compared and analyzed by structuring the data values as elements of n × n impedance matrix, and characterizing these matrices by their eigenvalues and eigenvectors. Another, not entirely exclusive subset of the data is alternatively processed, compared and analyzed by plotting the impedance data as chords of two circles representing the two homologous body regions. Impedance chord plots provide a visual indication of certain disease states and their location.
